Previously canRetry was attempting to retrieve this error from args, however there was never
any callers that would pass an error to args.
With the change to raftApply to move this error to the error return value, it is now possible
to receive this error from the err argument.
This commit updates canRetry to check for ErrChunkingResubmit in err.
Previously we were inconsistently checking the response for errors. This
PR moves the response-is-error check into raftApply, so that all callers
can look at only the error response, instead of having to know that
errors could come from two places.
This should expose a few more errors that were previously hidden because
in some calls to raftApply we were ignoring the response return value.
Also handle errors more consistently. In some cases we would log the
error before returning it. This can be very confusing because it can
result in the same error being logged multiple times. Instead return
a wrapped error.
Previously only a single auth method would be saved to the snapshot. This commit fixes the typo
and adds to the test, to show that all auth methods are now saved.
This way we avoid serializing these when empty. Otherwise users of the
latest version of the api submodule cannot interact with older versions
of Consul, because a new api client would send keys that the older Consul
doesn't recognize yet.
The zero value of these flags was already being excluded in the xDS
generation of circuit breaker/outlier detection config.
See: makeThresholdsIfNeeded and ToOutlierDetection.
This PR replaces the original boolean used to configure transparent
proxy mode. It was replaced with a string mode that can be set to:
- "": Empty string is the default for when the setting should be
defaulted from other configuration like config entries.
- "direct": Direct mode is how applications originally opted into the
mesh. Proxy listeners need to be dialed directly.
- "transparent": Transparent mode enables configuring Envoy as a
transparent proxy. Traffic must be captured and redirected to the
inbound and outbound listeners.
This PR also adds a struct for transparent proxy specific configuration.
Initially this is not stored as a pointer. Will revisit that decision
before GA.

This mostly affects streaming since streaming will immediately return from Fetch calls when the state is Closed on eviction which causes the race condition every time.
However this also affects all other cache types if the fetch call happens to return between the eviction and then next time around the Get loop by any client.
There is a separate bug that allows cache items to be evicted even when there are active clients which is the trigger here.
* Add changelog entry
